20 Feb 2018 LASER COMPONENTS is a world leading manufacturer of PbS and PbSe infrared detectors.
From our research and production facility in Arizona we supply customers all over the world
with these industrial grade thermal detectors.
These detectors work on the principle that photons incident on the Polycrystalline thin fi lm
promote electrons across the bandgap increasing the conductivity of the material, in turn
decreasing the resistance of the substance. The Polycrystalline lead sulphide (PbS) units
detect radiation in the wavelength range between 1 and 3.3 microns and exhibit a higher
sensitivity than Polycrystalline lead selenide (PbSe) which can detect radiation between 1
and 5.2 microns.
The devices are manufactured in standard TO style packages and have long expected lifetimes
making them ideal for fi t and forget applications such as gas sensing, surface inspection
and identifying the presence of a fl ame. The PB27 is a collection of thermo-electrically
cooled Polycrystalline biased single element PbS detectors with a 20% cut off at 3.3 microns
and a maximum element size of 3 x 3 mm2.
